Libvorbis Documentation

Libvorbis contains the Vorbis reference encoder and decoder.

This is the lowest-level interface to the Vorbis encoder and decoder. If you're just looking for a simple way to extract the audio from an Ogg Vorbis file, you probably want to use vorbisfile rather than using libogg and libvorbis directly.
